The document discusses the question of whether to use open educational resources (OER) or not. It defines OER as freely accessible and openly licensed documents and media that can be used for teaching, learning, and research. Some of the advantages of OER include reduced costs for students, access to materials before and after class, and resources tailored specifically for the student population. However, some drawbacks are that instructors do not profit from OER, the validity of information is sometimes questionable, searching for resources can be cumbersome, and cheating may occur more easily if all students have access to the same open materials.
